Google is going to start telling you if apps have adverts in them

Google is about to start warning you if the app you're
downloading contains adverts.

In an email sent to developers, Google says that from early
January 2016, all apps in the Google Play Store that contain
adverts will be labeled as such, and that developers need to
notify Google if this is the case for their apps.

The feature already exists for games that sit in the "Designed
for Families" category, but the search and mobile giant has
decided to extend the feature across its entire library.

Here's how that currently looks:

At Google I/O, we launched “ad-supported” labels for apps in the
Designed for Families program. Today, we’re announcing the
expansion of this program to all apps on Google Play. Early next
year, users will start to see the “Ads” label on apps that
contain advertising, both inside and outside Designed for
Families.

By January 11, 2016, you must sign in to the Play Developer
Console and declare whether your apps contain ads (such as ads
delivered through third party ad networks, display ads, native
ads, and/or banner ads). After this date, the ads declaration
will be required to make any updates to your apps. Please note
that misrepresenting ad presence violates Google Play Developer
Program Policies and may lead to suspension. You can visit our
help center to learn more.

While developers are responsible for accurately declaring ad
presence in their apps, Google may verify this at any time and
display the “Ads” label if appropriate.

If you feel your app has been incorrectly flagged for containing
ads, please contact our policy support team.
